Abstract: Method of controlling a hydrodynamic retarder in a motor vehicle which has a drive train comprising an internal combustion engine 1, a gearbox 2 driven by this via a clutch, a differential 5 connected to the latter either directly or via a universal shaft 4, a pair of half shafts 6 connected to the differential with wheels 7 located on the half shafts. To regulate the retarder (3) in a way maintaining velocity, an electrical angular velocity signal is constantly generated from the speed of one component or the average speed of a pair of components in that part of the drive train beginning with the output shaft of the gearbox (2) and ending with the wheels (7) and the instantaneous angular velocity signal is stored with the aid of a command generated by the "basic acceleration signal" from the accelerator basic position signal transmitter or by the brake signal from the brake pedal position signal transmitter indicating the various positions of the brake pedal. By means of the "basic accelerator signal" or the brake signal a control signal is fed to the electro-hydraulic valve system (13) of the hydrodynamic retarder (3), whereupon the angular velocity signal constantly relayed by the angular velocity signal transmitter (16) is constantly compared with the stored angular velocity signal and, should any difference occur between the two angular velocity signals, the control signal is modified in such a way that the value of the instantaneous angular velocity signal is returned towards the value of the stored angular velocity signal. <IMAGE>

Abstract: There is disclosed a process of treating meal containing vegetable proteins. This process includes the step of extracting the meal at an extraction and washing zone 10 with a suitable aqueous solvent, e.g. aqueous sodium hydroxide, in which the vegetable proteins are soluble to obtain an extraction solution. The wet residue is suitably separated, e.g. by filter 12, from the extraction solution, and dried in dryer 13 to provide a meal residue C. The solubility of the dissolved protein in the extraction solution is then adjusted in zone 14 to precipitate at least some of the protein and therefore obtain a precipitated protein fraction and an unprecipitated protein fraction in solution. The precipitated protein fraction is then separated from the protein fraction in solution, and the unprecipitated protein fraction is separated from the undesirable components in the solution by membrane processing in a zone 18. Each of the protein fractions is then suitably dried in dryers 17 and 19 to recover the proteins. This process provides a commercially viable process for producing pure, good-grade protein from rapeseed.

Abstract: The present invention relates to apparatus which acts to prevent flow of electrical current in an electrical power supply cable when the cable is damaged, or disconnected, at a part of the cable remote from the power source. 
     A transmitter is provided for connection to the cable at the end remote from the power source, and a control means is provided for connection between the power source and the cable. The transmitter transmits a signal down a cable conductor to the control means, which maintains the power supply connected to the cable as long as the signal is being received. If no signal is received by the control means, perhaps because of cable damage or disconnection, the control means causes the power source to be disconnected from the cable. 
     In a further embodiment, for further safety, a second transmitter is also provided with the control means for transmitting a further signal down the cable to the first transmitter. The first signal will not be transmitted unless the transmitter is itself receiving the further signal.

Abstract: Since a superconducting quantum interference device (SQUID) using a high temperature superconductor (1, 6, 7, 20) operates at the liquid nitrogen temperature 77 K, which is higher than the liquid helium temperature 4.2 K, it is necessary that the value of signal voltages is at a level, which is sufficiently higher than the thermal noise level. The superconducting inductance L should be decreased with increasing current flowing through Josephson junctions (2) in the SQUID. The superconducting inductance can be reduced by various methods such as reduction in the size of the aperture (3) of the superconducting inductance, parallel connection of superconducting inductances, utilization of a superconducting ground plane, etc., in order to realize a SQUID, which can be use in a wide application field at the liquid nitrogen temperature 77 K.

Abstract: An improved UV stabilized primer composition for providing an acrylic primer layer between a silicone top coat and a thermoplastic substrate, has been found to impart improved weathering resistance to silicone-coated thermoplastic articles. The primer composition includes respective amounts of 2-(2′-hydroxy-5′-t-octylphenyl)benzotriazole and nickel dibutyldithiocarbamate. The presence of nickel dibutyldithiocarbamate in the primer composition reduces the tendency of the 2-(2′-hydroxy-5′-t-octylphenyl)benzotriazole to crystallize during drying of the primer layer prior to top coating with the silicone hardcoat, as well as enhancing the UV protection of the system.

Abstract: A rear wheel turning mechanism in a four wheel steering system includes a rear wheel turning rod (30) which is connected to the rear wheels (6L, 6R) of the vehicle and is adapted such that it can be displaced and thereby turn the rear wheels. An electric motor (32) is operatively connected to the rear wheel turning rod and to the steering wheel (18) and displaces the rear wheel turning rod, thereby causing the rear wheels to turn in response to operation of the steering wheel. A rear-wheel-neutralizing spring (36) urges the rear wheel turning rod to the neutral position in which the rear wheels are held in the straight-ahead position. A pair of clutches (48) are interposed in series between the electric motor and the rear wheel turning rod and are adapted such that they disconnect the latter from the former, which permits the latter to return to the neutral position under the force of the rear-wheel-­neutralizing spring in case of failure of the rear wheel turning mechanism.

Abstract: An inverter power supply with improved power factor comprises a source of low frequency AC voltage and an inverter having a pair of series connected first and second transistors controlled to alternately turn on and off at a high frequency for providing a high frequency AC voltage to a load. A diode-bride full-wave rectifier is connected to provide a DC voltage which is charged to at least one capacitor which in turn provides a DC voltage input to the inverter. An inductor, which counteracts the capative reactance of the capacitor for improving the power factor, is inserted in series with the AC voltage source across the input of the diode-bridge rectifier. The first and second transistors of the inverter also operate to interrupt or chop at the high frequency a current fed through the inductor from the AC voltage source so as to charge the capacitor through the rectifier by the inductor. During each one cycle of the AC voltage from the AC voltage source, the first and second transistors are both serve to chop the current through the inductor for charging the capacitor as well as to provide the current to the load. Further, the rectifier shares at least two diodes of the inverter for establishing a loop for charging the capacitor.

Abstract: To produce a dual reflector antenna system capable of passing radiation to or from a shaped coverage area by means of a single feed (1), a three dimensional main reflector surface (3) and a three dimensional sub-reflector surface (2), a method is employed which includes defining desired levels and/or characteristics of radiation incident upon or received from selected regions of said coverage area, and optimising actual radiation levels and/or characteristics for said regions by modifying both said reflector surfaces (2,3) simultaneously. 
     The optimisation is achieved by iteratively determining levels and/or characteristics of radiation incident upon or received from each of said regions and obtaining the least favourable value of level and/or characteristic and modifying said reflector surfaces (2,3) simultaneously to obtain an improved least favourable value of level and/or characteristic.
